E8055
Motor overload, current limit active
Bosch Rexroth · IndraDrive C Drive Controllers
What does E8055 mean?
The motor is experiencing an overload condition, and its current has reached the configured limit. This indicates that the motor is being driven beyond its continuous operating capacity, posing a risk of overheating.
Common Causes
- Excessive mechanical load on the motor.
- Continuous operation above the motor's rated current.
- Incorrect motor parameters in the drive's configuration.
- Mechanical binding or obstruction in the system.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Reduce the mechanical load on the motor to within its continuous operating specifications.
- 2
Verify that the motor parameters (e.g., rated current, thermal model) in the drive are correctly configured to match the motor nameplate.
- 3
Inspect the mechanical system for any binding, misalignment, or excessive friction that could cause an overload.
- 4
Check the application's duty cycle to ensure the motor is not continuously operating in overload conditions.
